To all whom it may concern.- which lies adjacent to the disk, caused by Be it known that I, FRANK R. PACKHAM, a gritty substances impinging between it and citizen of the United States,residing at Sprin gthe disk, greatly diminishes the efficiency of field, in the county of Clark and State of Ohio, the shield, and to obviate this without em- 5 have invented certain new and useful Imploying devices to reset the shield I preferprovements in Grain-Drills, of which the folably cast the shield and the parts formed lowing is a specification. therewith of malleable metal, so that when My invention relates to furrow-openers for the edge of the shield becomes worn, leaving seeding implements, and more particularly a space between it and the disk, the space 10 to that class of implements where the trench can be quickly closed by hammering the edge or furrow for the reception of the seed is of the shield back into position adjacent to opened by a disk. the disk. This may be quickly and easily The object of my invention is to improve done by the operator and it will immediately the construction of the disk-carrying frame, restore the efficiency of the shield.

The free operation of the disk under the The wear on the front edge of the shield, varying angular changes incident to its rise and fall and the necessity of delivering the grain close to the face of the disk has given considerable trouble to properly deliver the grain to the grain-conduit of the disk-support. Heretofore the grain-conduits of the disk-supports have been usually formed integrally with the supports extended high up and with liberal dimensions to permit the telescoping conductingspouts to operate without cramping. This construction required a heavy cumbersome casting, and even this did not in all cases avoid the difficulty of the telescoping spouts contacting and interfering with the free operation of the disk upon its rise and fall over uneven ground or obstructions. Another difficulty has been the carrying up by the disk of adhering mud that would interfere with the operation of the telescoping spouts, as hereinbefore described. To overcome these difliculties and avoid the heavy casting of the old construction, I make the grain-conduit a short in its extended portion, to which any suitable universal-joint connection may be made with the seed-conductor from the hopper. Preferably I form this universal joint by providing a flange a at the lower edge of the seed-conductor a to rest on top of the conduit portion a of the frame, and I further provide a cap a for said conduit portion, which I have shown attached to same by a screw a in such manner that inwardly-extending flanges a of the cap form a chamber to confine the flange a and yet allow sufficient play to the seed-conductor, as more particularly shown by the dotted lines in Fig. 6, to compensate for the rise and fall of the disk frame. In Figs. '7, 8, and 9 I have shown other forms of universal joints; but I do not wish to confine myself to any particular form, as any well-known form will answer, although the one I have described and shown in Fig. 6 is the preferred form. I furtherprovide a washer or head-cup a over the cap a", which slides on the conductor a to protect the universal joint from foreign substances.

The seed-conductor tube a leading from the grain-distributor of the hopper, I telescope into the lower section a of the tube, and thereby form a closed conduit from the hopper to the furrow, that will automatically adjust itself to the rise and fall of the furrow-opener, and the telescoping portion will not at any time extend beyond the axial center of the disk, which is very objectionable in all previous devices. The conductors a and a I preferably form of non-collapsible material, preferably thin metal, which in connection with the universal joint, as described, the use of which enables me to shorten the seed-receiving conduit or, makes a saving in weight alone of some forty pounds in an ordinary-sized drill. It will thus be seen that in addition to its increased efliciency the improvement is of great economy in manufacture.

The cap a is preferably formed integrally with the rearwardly-extending portion a and becomes the means of attaching said portion to the disk-frame, as shown in Figs. 1 and2; but I may modify this construction, as shown in Fig. 5, wherein I have shown the portion a formed integrally with the disk-frame and shield and the cap a independent thereof.

I provide the disk-frame with an extension o to which I secure the lower end of the drag-bar d by rivets (i but it may be socured in any suitable manner, and said bar is pivoted at d to the main frame of the machine. On the rearwardly-extending part a I provide a perforation with a set-screw or to secure the shank a of a scraper to operate on the concave side of the disk, and I further provide an opening a, to which I pivot a pressure-spring rod 6, operated by a rock-shaft c and a hand-lever on said shaft.

Having thus described my invention, I claim 1. In a disk drill, the combination of a support having a grain-conduit, a furrow-opening disk journaled on said support, a grainconductor and a universal joint connecting said conduit and conductor, substantially as specified.

8. In a disk drill, the combination of a support, a disk journaled at an angle to the line of draft to said support, said support being formed with a grain-conduit in its upper portion and havinga shield extending below and in front of said cond uit,its front portion adapted to conform with and lie adjacent to the face of said disk to a point removed from its periphery, and a cleaner adapted to contact with and clean that portion of the disk to which said shield does not lie adjacent, a grain-conductor having a flange adapted to rest on said support about said grain-conduit, and a cap attached to said support, extended over said conductor-flange, adapted to form a loose connection, permitting a lateral and longitudinal movement of said conductor, substantially as specified.

In testimony whereof I have hereunto set my hand this 20th day of June, A. D. 1902.
